Here are a few commands that work well on Unix/Linux systems. Adjust the directory (`.` is current directory) as needed.\n\n---\n\n## \u2705 Using `find`\n\n```bash\nfind . -type f -mtime -365 -exec ls -l {} +\n```\n\n- `.` \u2192 start in the current directory  \n- `-type f` \u2192 only regular files (not directories)  \n- `-mtime -365` \u2192 modified *less than* 365 days ago (i.e. in the last year)  \n- `-exec ls -l {} +` \u2192 list each matched file in long format using `ls -l` ([linuxuprising.com](https://www.linuxuprising.com/2020/09/how-to-find-files-modified-in-last-n.html?utm_source=openai))\n\nIf you want the results sorted by modification date, newest first:\n\n```bash\nfind . -type f -mtime -365 -printf \"%T@ %Tc %p\\n\" | sort -nr\n```\n\n- `%T@` gives a numeric timestamp for sorting  \n- `%Tc` gives human-readable time  \n- `%p` gives the file path ([smallsharpsoftwaretools.com](https://smallsharpsoftwaretools.com/tips/find-modified-files/?utm_source=openai))\n\n---\n\n## \u26a0 Why not only `ls`\n\nA pure `ls` command can sort by modification time (`-t`) and show files modified recently at the top, but it **cannot filter** by a time span (like \u201clast year\u201d) by itself:\n\n```bash\nls -lt         # sorts by modification time, newest first\nls -lt --full-time | grep '2025-'  # crude hack to filter by year in filename time field\n```\n\nBut such hacks are unreliable (e.g. for dates beyond a certain default cutoff) and don\u2019t always capture exactly \u201cin the past year.\u201d ([superuser.com](https://superuser.com/questions/1923840/why-does-the-ls-command-show-some-files-with-a-year-and-others-with-a-time?utm_source=openai))\n\n---\n\nIf you tell me whether you want to include subdirectories, or want a specific format (just filenames vs full details), I can give a more tailored command."
